Welcome!

Everyone knows it. Pools affect us in a deep way. Everyone here at hydro+logic has had that magic refine us into lovers of the craft of creating these places of wonder. Our mission is to share our passion and knowledge with everyone else who feels as we do. Thank you for being here!

We often get asked about capacity for pools during the planning process. The challenge we find is there are different meanings for “capacity” depending on who you are talking to. Sometimes people want to know how many people can fit in the pool, sometimes they want to know how many people they can allow in the gates, and other times they want to know how many people they could accommodate over an entire day.

The term “Frozen Capacity” refers to the maximum capacity in a facility at one time, which is, understandably, the peak period for the day, whether it is an indoor facility or an outdoor facility. There does not exist a comprehensive formula but a combination of ratios currently used in the industry and is used to determine bather load and frozen capacity.

The majority of health departments in the U.S. use the following formula for bather load sizing; shallow water = <1500 x water depth: = 1 person/3M², (includes wading pool)
